Querying the List of Central Network Connections

Function

This API is used to query the list of central network connections.

Parameters marker and limit are used for pagination query. The default value of limit is 0. If marker is not specified, the first data record is returned.

URI

GET /v3/{domain_id}/gcn/central-network/{central_network_id}/connections

Table 1 Path Parameters

Parameter	Mandatory	Type	Description
domain_id	Yes	String	Account ID.
central_network_id	Yes	String	Central network ID.

Table 2 Query Parameters

Parameter	Mandatory	Type	Description
limit	No	Integer	Number of records returned on each page. The value ranges from 1 to 2000.
marker	No	String	Pagination query information. You can obtain the marker values from the response of the last API call. You can enter the marker value of the previous page or the next page. If you enter the marker value of the previous page, the previous page will be queried. If you enter the marker value of the next page, the next page will be queried. During pagination query, the query criteria, including the filters, sorting criteria, and the limit value, cannot be modified.
sort_key	No	String	Field for sorting.
sort_dir	No	Object	Whether the resources are sorted in ascending or descending order. asc indicates the ascending order and desc indicates the descending order.
id	No	Array of strings	Resource ID. Multiple IDs can be queried.
name	No	Array of strings	The resource name used for query. Multiple names can be specified for query.
state	No	Array of strings	Resource status. Multiple statuses can be used for query. AVAILABLE CREATING UPDATING DELETING FREEZING UNFREEZING RECOVERING FAILED DELETED APPROVING APPROVED UNAPPROVED
global_connection_bandwidth_id	No	Array of strings	Bandwidth package IDs.
bandwidth_type	No	Object	Bandwidth type. The bandwidth types are as follows: BandwidthPackage: A global connection bandwidth billed by fixed bandwidth is required, and cross-site connection bandwidths are assigned from the global connection bandwidth. TestBandwidth: The test bandwidth is free. Only the minimum bandwidth is used for testing cross-region connectivity.
connection_type	No	Object	Type of a central network connection. Multiple types can be used for query. ER-ER: connections between enterprise routers ER-GDGW: connections between enterprise routers and global DC gateways ER-ER_ROUTE_TABLE: connections between enterprise routers and route tables of other enterprise routers
is_cross_region	No	Boolean	Whether there are different regions.

Request Parameters

Table 3 Request header parameters

Table 5 PageInfo

Parameter	Type	Description
next_marker	String	Backward pagination identifier.

Table 6 CentralNetworkConnection

Parameter	Type	Description
id	String	Instance ID.
name	String	Instance name.
description	String	Resource description. Angle brackets (<>) are not allowed.
domain_id	String	ID of the account that the instance belongs to.
enterprise_project_id	String	ID of the enterprise project that the resource belongs to.
central_network_id	String	Central network ID.
central_network_plane_id	String	ID of the central network plane.
global_connection_bandwidth_id	String	Global connection bandwidth ID. If bandwidth_type is set to TestBandwidth, no global connection bandwidth is bound, and this parameter is not displayed.
bandwidth_type	String	Bandwidth type. The bandwidth types are as follows: BandwidthPackage: A global connection bandwidth billed by fixed bandwidth is required, and cross-site connection bandwidths are assigned from the global connection bandwidth. TestBandwidth: The test bandwidth is free. Only the minimum bandwidth is used for testing cross-region connectivity.
bandwidth_size	Long	Bandwidth range, in Mbit/s. If bandwidth_type is set to TestBandwidth, the bandwidth size is the default value, and this parameter is not displayed.
state	String	Central network connection status. AVAILABLE CREATING UPDATING DELETING FREEZING UNFREEZING RECOVERING FAILED DELETED APPROVING APPROVED UNAPPROVED
is_frozen	Boolean	Whether the resource is frozen.
connection_type	String	Type of a central network connection. ER-ER: peering connection between enterprise routers ER-GDGW: connection between an enterprise router and a global DC gateway ER-ER_ROUTE_TABLE: connection between an enterprise router and an enterprise router route table
connection_point_pair	Array of ConnectionPoint objects	Both ends of a central network connection. The length is fixed to an array of 2.
created_at	String	Time when the resource was created. The UTC time is in the yyyy-MM-ddTHH:mm:ss format.
updated_at	String	Time when the resource was updated. The UTC time must be in the yyyy-MM-ddTHH:mm:ss format.

Table 7 ConnectionPoint

Parameter	Type	Description
id	String	Instance ID.
project_id	String	Project ID.
region_id	String	Region ID.
site_code	String	Site code. You can obtain the code by calling the API for querying the site list of the global connection bandwidth.
instance_id	String	Instance ID at an end of a connection.
parent_instance_id	String	Parent resource ID of the instance at an end of a connection.
type	String	Type of the resource that can be added to a central network as an attachment. ER: enterprise router GDGW: global DC gateway ER_ROUTE_TABLE: enterprise router route table
